摘要:
A method self-adapts signal quality of non-audio data exchanged via an audio channel between a mobile terminal and a payment accessory. The method includes at least one iteration of the following acts: reception, by the mobile terminal, of a reference signal transmitted by the payment accessory; analysis, in the mobile terminal, of the received reference signal, the analysis delivering at least one item of information representative of the quality of the reference signal, referred to as quality information; transmission, by the mobile terminal to the payment accessory, of the quality information. In the above iteration, the roles of the mobile terminal and the payment accessory can be switched.
摘要:
A method for processing transaction data, implemented by a communications terminal having a touch screen. The method includes: detecting a necessity of entering a piece of personal identification data; transmitting to a card reader connected to the communications terminal a request for supporting a display of a virtual keypad, the request comprising a piece of data representing a passage of the communications terminal from a “master” mode to a “slave” mode of operation, the slave mode leading to implementation of the method for processing transaction data under the exclusive control of the card reader; of entry, by the user on the virtual keypad, of the piece of personal identification data; and receiving, from the card reader, the piece of personal identification data.
摘要:
A method for pairing a first terminal, called a communications terminal, seeking to transmit and receive data with a second terminal, called an acceptor terminal. The method includes: a first non-secured pairing phase for pairing the transactional terminal with the communications terminal, delivering at least one pairing parameter for pairing with the communications terminal, by using a first radio-type bidirectional wireless communications channel; a second phase of secured pairing of the transactional terminal with the communications terminal, the second pairing phase implementing a second unidirectional communications channel used by the transactional terminal to transmit a piece of securing data from the first communications channel to the communications terminal, as a function of the at least one parameter for pairing with the communications terminal.
